Answer:

y = -
(1)/(2) x + 1

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line

m =
(-1-1)/(4-0) =
(-2)/(4) = -
(1)/(2)

The line crosses the y- axis at (0, 1 ) ⇒ c = 1

y = -
(1)/(2) x + 1 ← equation of line
